Further analysis did not show any expansion in the levels of CD33+CD11b+ cells (HD; 74.6 ± 2.6 vs PBC; 74.3 ± 3.0; Fig. 2b) and CD33+CD11b+HLA-DR−/low cells in PBC patients compared with HD (HD; 70.9 ± 2.4 vs PBC; 71.4 ± 3.4; Fig. 2c). This evidence concerns the gene CD33 and primary biliary cholangitis.
